JOHN NUTRY, OF BROOKLYN, NEXV YORK.

INSTRUMENT FOR INDICATING AND RECORDING THE SPEED OF VEHICLES.

SPECIIEIL'CAIION forming part of Letters Patent No. 702,110, dated June 10, 1902.

Application filed July 26, 1901.

To all whom it may concern:

Be it known that I,JOHN NUTRY, a citizen of the United States, residing in Brooklyn, city and State of New York, have invented a new and useful Improvement in Instruments for Indicating and Recording the Speed of Vehicles, of which the following is a specification.

The objectof this invention is to make an instrument that will exhibit plainly to the eye the rate of speed of the vehicle and also to make a permanent record of the speed and distance traveled.

The accompanying drawings, forming part of this specification, show the construction and arrangement of parts, in which Figure 1 is a section through the middle. Fig. 2 is an elevation of the speed-indicator portion. Fig. 3 is an elevation of the recording portion. Fig. 4 is an elevation of indicator-dial, reduced size. Fig. 5 is the ribbon on which record is made.

Like letters refer to like parts.

The instrument in the form as here shown is contained in a cylindrical case A in two sections A and A The driving-wheel S can be a sprocket, gear, or pulley on shaft S. Section A contains the mechanism for the indicator, and section A the recording mechanism. In section 'A is a compartment A containing a timepiece or clock-movement that operates the shaft A on which is a drum T and disk T connected together and driven by frictional contact with the shaft A. Fixed to the wall of compartment A is a plate T flush with the face of disk T, on which is a stud to hold a spool for the supply of ribbon T. At the other end is a hinged arm T, on which is a'revolving disk T the disk being held in contact with disk T by spring T pressing against the arm T The disk T carries a spool on which the ribbon is wound after the record has been made on it. The ribbon T has a line of perforations T, Fig. 5, and is marked for hours and portions of hours. The ribbon is placed in the instrument so that it passes over the drum T, the points on the drum entering the perforations in the ribbon, so that the ribbon moves at the speed of the drum, which in this case is one revolution in one hour. Fixed to the wall of compartment A is a bracket L and Serial No. 69,759. (No model.)

hinged to it is a piece L so formed as to hold the ribbon onto the drum and slotted so as to allow the ribbon to be perforated by the needle L The cylinder A can be hinged or otherwise made to separate from cylinder A for the purpose of changing the record-ribbon. The needle L is connected to and operated by the mechanism in cylinder A. It is fixed to lever L and held in position by spring L The lever L is held in position by spring L and is operated by a cam O on shaft W moving against a projection on lever L, the lever L being held in contact with the cam by spring L. The shaft V1 on which the cam is fixed, is driven by worm-wheel W and that by worm "W on shaft W, which is driven by worm-wheel S and worm S on shaft S and through wheel S, connected to a wheel of the vehicle, each revolution of the cam recording a definite distance traveled.

N is a support attached to the case, by which it can be fixed to the vehicle.

At one end of the cylindrical case is a dial for showing the speed of the vehicle. Its face is of glass A, with the dial D back of the glass and pointer D between glass and dial.

D is the shaft, carrying the pointer and a pinion Q Geared with the pinion is a quadrant Q, hung or pivoted on the front plate of cylinder A and havin arm Q, extending between collars on sleeve G which slides on shaft S. Fixed to shaft S is a hub and frame carrying arms and balls G, which are hung or pivoted at G in the frame and having arms G extending between collars on the sleeve G F is a frame fixed into the cylinder-case A for the support of shafts W and D The operation of the invention is as follows: The instrument is attached to a suitable part of the vehicle. The wheel Sis geared so as to be driven at a. determined ratio of speed from one of the wheels of the vehicle. The balls G fly out by centrifugal force from the shaft S to a degree proportionate to the speed of'the vehicle and by the arms G carry the sleeve along the shaft S against a spring (not shown) of any suitable form and moves the quadrant Q in like proportion through the lever Q. The quadrant being in gear with pinion QP moves the shaft l) and the pointer D over the face of the dial to markings indicating speeds. Any change of speed of the vehicle Will show a corresponding change in the position of the pointer on the dial. At the same time the shaft S communicates motion to the Worm-Wheel S on shaft W' and by Worm W to Worm-Wheel W on shaft W Having described my invention, What I claim, and desire to secure by Letters Patent, 1S

In an instrument for indicating and recording the speed of vehicles, a centrifugal governor with means for attaching to vehicle and suitable gearing to operate it from a wheel of the vehicle, a slide on the governor-shaft operated by the governor, a quadrant or section of a Wheel connected to and moved by the slide, a pinion geared to and driven by the quadrant, a pointer fixed to the pinionslot for the entrance of the needle; in combination with a drum driven by a clock-movement and arranged to carry a ribbon against the platen, the lever and needle being arranged to perforate the ribbon with a straight line of holes, substantially as shown and described.

JOHN NUTRY.
